Quote #7
Thus, my boy, be bold and opt for me, the Better Argument. / You shall learn to loathe the market, to shun the public baths as well, / to feel ashamed of what is shameful, to burn with rage at any slight, / to offer your seat to any grownup you may see approaching you; / never to treat your parents rudely, never to act disgracefully / or any way that might dishonor the sacred shrine of Modesty; / never to invade a go-go dancer's house and lose your head, / making the whore get sweet on you, thus shattering your good repute; / never to contradict your father, calling him Methuselah, / laughing at how old he is, forgetting how he reared you! (990-999)
Better Argument gets into even more detail here about things that are (in his view) inherently good or evil. Good things include respecting your elders, pride, and acting in a dignified way.
Quote #8
I got the name Worse Argument among the intellectuals / for just this very reason, that I pioneered a new technique, / a logical way to contradict established laws and morals. (1038-1040)
Meanwhile, Worse Argument really doesn't give a hoot about right and wrong or "established morals," and he makes his living teaching people how to argue for what they want and get it, regardless of "established laws and morals."
Quote #9
Hurrah, hurrah, my child! Wow, / how great it is to see your pale complexion! / You're obviously ready to take the fifth, / to rebut accusers. You've sprouted that true Athenian / expression, the Who-Me? Look of being wronged / when you're guilty, even of serious crimes. I know / that look, and I see it blooming on your face! / So save me, since it was you that ruined me. (1170-1177)
Strepsiades is ecstatic because he believes (based on Pheidippides's paleness, which means he's been inside the Thinkery learning) that his son is ready to help him execute his nefarious plan.
